Dairymac AI Gun Superwarmer™ - Dairymac

Dairymac AI Gun Superwarmer™

The Dairymac A.i. Gun Superwarmer™ was developed to improve semen handling and conception rates in Cows. As farming becomes more sophisticated and farmers rely on top quality semen from the world’s best bulls, the importance of correct semen storage, handling, thawing and the actual insemination process to the cow is paramount.

The Dairymac A.i. Gun Superwarmer™ offers a temperature-controlled environment for A.i. Guns which have been loaded with straws of freshly thawed Bull Semen.

Semen Handling Procedure

The Bull Semen will have been stored in plastic straws and removed from liquid Nitrogen at -196°C (-320°F) and then usually thawed with a Dairymac Superthaw™ to 36° (96°F) or 37°C (98°F). The straw is then inserted into a stainless-steel A.i Gun, the tip snipped off and a protective sheath put over the top. Good practice is to also cover the A.i. Gun with a plastic chemise to stop Faecal contamination.

After this the traditional method of keeping the ‘loaded Ai Gun with thawed semen inside is to stick it down your back, with the vague home that your own body temperature will keep the semen warm and alive.

This is clearly not best practice.

The Dairymac A.i. Gun Superwarmer™ is a temperature-controlled environment which can keep the semen alive for several hours, although it is considered best to try and get the semen into the cow with 10-20 minutes.

Every farmer or technician knows the panic of carrying several loaded A.i. Guns around trying to manoeuvre cattle in a chute and losing valuable minutes.

The Dairymac A.i. Gun Superwarmer™ takes this panic away.

Quite simply it does a better job at keeping Bull Semen warm, this is particularly important in the colder winter months where the A.i. Technicians own body temperature can wildly fluctuate.
